General DescriptionSeries AVF (Hydraulic) adjustable velocity fuses aredesigned to provide automatic hydraulic line ruptureshut-off, as well as the ability to isolate a problemcircuit on parallel circuit applications. Use of the fuseslimits oil spillage and potential component damage.The fuses feature an adjustable flow for easy set-upand operation. A set screw in the body is provided to“lock in” the selected flow.
Features
• Provides automatic line rupture shut-off.
• Isolates problem circuit on parallel circuit applications.
• Limits oil spillage and potential component damage.
• Adjustable closing flow — simple readjustment.

Technical InformationCheck ValvesSeries AVF – Hydraulic
Operation
Series AVF adjustable velocity fuse is a normally open,in-line valve. Under normal conditions, a spring holdsthe fuse poppet off its seat.
Flow Path
Flow enters the fuse at the flanged inlet port (A).Before reaching the poppet, a series of radial holes (B)in the body directs flow from the body core into anannular cavity (C) between the body and the adjustingsleeve. Flow is directed axially between the body andsleeve until it reaches another series of radial holes (D)at the poppet seat. Flow is then directed back into thebody core through the seat and out the fuse outlet port(E).
Making Adjustments
External adjustments of the sleeve reduce the “free”area of the radial holes (D). This reduction in areacreates an increase in flow velocity, resulting in ahigher pressure drop. When the pressure drop exceedsthe spring force holding the poppet open, the inletpressure will force the poppet against its seat, effec-tively closing the fuse.
Line Rupture Shut-Off
The sleeve can be adjusted such that, at normal flows,the fuse will remain open but increased flow rates(such as caused by downstream line rupture) will resultin a rapid closing of the fuse. The fuse will remainclosed until the inlet pressure is eliminated or thedownstream pressure is equalized with the inlet.

Check ValvesSeries AVF – HydraulicApplications
Conventional Fuse
• Closing flow must be calculated
• Calculation error results in unusable valve
• System changes make valve unusable
• “Matched” fuses are very expensive
• Special order to meet requirements
AVF Series Adjustable Velocity Fuse
• No calculations required
• Correct size always supplied
• Simple re-adjustment
• Minor adjustment only
• Stocked by pipe size
Pump/System Air Bleed
When starting a pump under load, the blocked port resists flow,and more torque is required from the prime mover. This conditionmay cause an electric motor to draw higher “pull-up current,” ormay cause a combustion engine powered pump to stall. Thevelocity fuse is normally open and when tied into the tank, it willprovide an open, load free path to tank when the pump firststarts. As the pump nears operating speed, the resulting flow willcause the fuse to close, directing all flow into the primary circuit.
Main Pressure Line from Pump to Manifold
A line rupture in a central power unit would allow fluid to bepumped out through the broken line. The loss of oil can beexpensive to clean up, dispose of, and replace; plus it must bedone in accordance with EPA regulations. Ruptured lines maycause physical damage or the release of oil into a flammablearea. A velocity fuse closes down flow when failure of a lineoccurs and eliminates these problems.
Cylinder/Actuator Shut-Off
A line rupture that occurs when a cylinder is supporting a loadallows the load to fall unrestricted. A velocity fuse installed at thecylinder port will shut off flow and prevent the load from falling inthe event of a hose or tubing failure.

General Description
Series AVF (Pneumatic) adjustable velocity fuses aredesigned to provide automatic air line shut-off if a lineshould rupture or break. The use of fuses limits thepossibility of personal injury or damage to equipmentfrom whipping hoses. The fuses are field adjustable foreasy setup and operation. A set screw in the bodyallows the selected setting to be locked.
Features
• Provides automatic line rupture shut-off.
• Limits runaway conditions.
• Eliminates hose whip.
• Air or water compatible.
Benefits
• Eliminates “line whip.” No injury or damage possible.
• Limits runaway conditions. Load will stay in place afterbreak.
• Precise sizing not required. Each valve has an adjustableflow range.
• Simple readjustments. Turn barrel to reset.
• Setting may be locked.
• Four sizes available.
• Resets quickly after line repair. Pressurize downstream line.

Technical InformationCheck ValvesSeries 6C
General Description
Series 6C check valves provide free flow in onedirection and dependable shut-off in the reversedirection.
Operation
When pressure going through the valve is increased tothe cracking level, the valve opens. When the pressureis reduced to below the cracking level, the valvecloses.
Features
• Meets ISO 6149 standards.
• Hard metric dimensions.
• Reliable leak-free performance — straight thread port witho-ring sealing.
• Global interchangeablility.

Technical InformationCheck ValvesSeries VCL
General Description
Series VCL check valves operate at free flow in onedirection. Reverse flow is blocked.
Operation
The spring keeps the poppet closed until the valvereaches the preset pressure. The valve stays openuntil the pressure goes below the spring setting.
Features
• Available in a wide variety of crack pressures.
• Poppet spring is isolated from liquid flow streamminimizing turbulence.
• Close tolerance fit between poppet and poppet retainercreates a cushion that protects valve from surge shockdamage.

Technical InformationCheck ValvesSeries LT, LTF
General Description
Series LT and LTF Valves will operate satisfactorilywhen installed in any position. These valves may beused as Line Check Valves, permitting full flow ofhydraulic oil in one direction only or they may be usedas restrictors.
An assortment of restrictors are available. Wheninstalled, the valve becomes a Line Throttle Valvepermitting free flow of hydraulic oil in one direction anda restricted flow in the opposite direction.
An array of color-coded poppets allows easy and quickidentification.
Features
• Accurate control of double-acting cylinder by having bothsides of the piston pressurized.
• For improving control of the lowering stroke of a cylinder.
• For preventing cavitation of a cylinder or motor having aninertia load.
• For metering oil flow to a hydraulic motor for proper motorspeed.
• For improving control of the extend stroke of a hydrauliccylinder.
• Unidirectional.
